Sigma Lens Serial Number Lookup

It is possible as the USB Dock recognizes the serial number of products. Even though you have 2 pieces of 1 lens, the software will not mix up the lens information and each customization. Does the software offer off-line operation? Firmware updating and the lenses connected to the USB Dock for the first time require internet access. Sigma Lens Abbreviations. These lenses place its importance on optical performance and power. Expect these to have very wide apertures across fisheye, wide-angle, zoom and macro lenses. APO – Apochromatic. These lens elements reduce chromatic and other aberrations. They also bring a stronger contrast, color definition,. The lens I received is a XXmm f/XX lens for my XXXXX brand camera, and has serial number #233XXXX. The lens you received has a serial number which has not been issued by Sigma's factory in Japan. It appears that the lens you received is a 'Gray Market' lens, and has been tampered with having its serial number changed. I called to Sigma service and they said there's no firmware update for Sigma 150-500 so I have to buy a new lens. I guess the newer version of Sigma 150-500 (new stabilizer) with 8 digits in the serial number work fine with D7k? Does someone have an older version (7 digits in the serial) which autofocus in live view mode with the D7k? . Does not include serial numbers 900001 to 902908. These numbers were used on Sigma-Martins back in 1981-1982.

How old is your Canon lens? With either the lens' serial number or date code, that question can be answered.

Canon has been transitioning to a 10-digit lens serial number (starting in 2008 with the Canon EF-S 18-200mm f/3.5-5.6 IS Lens) and ending the inclusion of a separate manufacturing date code. While date codes and the shorter serial number are still found on some lenses, this inclusion will likely end completely. We loved the date code because it made aging a lens easy. However, now we can age a lens based on the serial number alone.

For information on determining the age of a pre-10-digit serial number lens, see the section on interpreting the old date code below.

Determine the age of a Canon lens based on the 10-digit serial number

To age a Canon lens using the 10-digital serial number, we dissect the serial number as follows:

DD C SSSSSSS

The DD is the key to the date the lens was manufactured - the production date code. The Canon lens date code chart is shown below.

These dates should be viewed as approximations and should be used for your amusement as the estimates are not guaranteed correct. Please send any discrepancies you find. Note that Canon EOS DSLR camera body serial numbers, at least for 2013, do not follow this chart. Also please note that future dates shown in the table are predictions/expectations.

The third digit in the serial number, C, may be a charge/batch type of number. Canon has been using this number to indicate lenses needing specific service-related updates such as firmware.

The remaining digits in the serial number, SSSSSSS, are a uniquely-identifying number of the lens – likely within the production month.

Please note that, while the overall chart is holding out nicely with the lenses we've checked (including several late-2014 models), it is a work-in-process. In part, the numbers might be shifted by a month or so. Again, please send us any discrepancies you find.

Special thanks go out to friend-of-the-site Norbert for his role in the development of this chart.

To determine the age of a pre-10-digit serial number Canon lens bearing a date code

Until phasing out the practice starting in 2008, Canon included a date code beside the rear lens element of many (but not all) lenses (note that some 2012-manufactured lenses retain the date code). The date code (as seen below) is in the form of 'UR0902'. This code is also present on some other Canon products including camera bodies.

The first letter, 'U', indicates that the lens was made in Canon's Utsunomiya, Japan factory. Prior to 1986, this letter is moved to the last position of the date code.

U = Utsunomiya, Japan
F = Fukushima, Japan
O = Oita, Japan

The second letter, 'R', is a year code that indicates the year of manufacture. Canon increments this letter each year starting with A in 1986 and prior to that, A in 1960 without the leading factory code. Here is a table to make things simple:

A = 2012, 1986, 1960
B = 2013, 1987, 1961
C = 2014, 1988, 1962
D = 2015, 1989, 1963
E = 2016, 1990, 1964
F = 2017, 1991, 1965
G = 2018, 1992, 1966
H = 2019, 1993, 1967
I = 1994, 1968
J = 1995, 1969
K = 1996, 1970
L = 1997, 1971
M = 1998, 1972
N = 1999, 1973
O = 2000, 1974
P = 2001, 1975
Q = 2002, 1976
R = 2003, 1977
S = 2004, 1978
T = 2005, 1979
U = 2006, 1980
V = 2007, 1981
W = 2008, 1982
X = 2009, 1983
Y = 2010, 1984
Z = 2011, 1985

The first two numbers, '09', is the month number the lens was manufactured in. Month 02 is February, month 11 = November. The leading zero of the month code is sometimes omitted.

Stolen Camera Database

The next two numbers, '02', are meaningless in determining how old a Canon lens is. This is a Canon internal code (that is occasionally omitted).

You now know the manufacture date for your lens - But - You cannot know how long the lens was in inventory, in shipping transit and on a shelf until it was originally purchased (without having the original receipt or a reputable person accurately informing you).

The Canon lens date code in the sample picture indicates that this Canon EF 24-70mm f/2.8L Lens (I know the lens model because I took the picture - not from the date code) was made in Utsunomiya, Japan in September 2003.
